I think that typically our ancestors were skilled at many more things than we are. There were no stores to buy things.

Today we each ‘specialize’ to survive. We do our ‘job’ well to get money. Does that mean our ancestors were less intelligent? How many of us know how to make aspirin? How many don’t know what poison ivy looks like ?

Sometimes I think that our ancestors were smarter than us, and that previous unremembered civilizations were much more advanced (or made advanced use of the ‘environment’ at the time).

I found something interesting and new to me. I had heard of the claim that the Covenant of the Ark was in Ethiopia, but I had not before heard of or seen the Rock Hewn Churches there in Lalibela (eleven churches carved in the ground out of the solid rock of a mountain, each with an underground spring well).

To give this some scale, the little white things in the lower left corner are houses.

Maybe you could feature it in a thread sometime. The history of it is very interesting.
